Ranger acquires American Well Services for $90.5 million, adding 39 workover rigs and boosting its fleet by 25%.
In this case study, a geomechanics-based approach was used to create bridging and sealing at the fracture aperture using a biparticle self-degradable lost-circulation-fluid system.
Operators from across the region met in Muscat to share how lessons from pilot programs are shaping cost, scale, and technology priorities across the region.

This paper focuses on identifying a hydrofluoric-acid-derivative treatment that could be used as a single-step sandstone-acid treatment with all the associated benefits but without the need for acid-flowback services. -
To improve the productivity index of a well in a carbonate reservoir offshore Abu Dhabi, a multilateral acid-jetting technology was adopted as a more-effective alternative to typical drainage methods.
-
This paper explores a holistic approach to characterize trouble stages by applying automated event recognition of abnormal pressure increases and associating those events with formation and operational causes.
-
The authors describe the applicability of 110,000-psi yield-strength quench-and-tempered coiled tubing strings in high-pressure sour environments through implementation of a custom-fit coiled tubing integrity and risk-mitigation program.
-
In this paper, the authors discuss what components have contributed to recent proppant-placement cost reductions and use several case studies to illustrate the potential for further cost reductions.
-
This paper describes a new concept for a reel mover used for coiled tubing deployment and operation.
-
In this year’s feature are two case histories and an equipment-development paper, all of which are, by accident rather than design, from operations undertaken in the Gulf States. Each, in its own way, exemplifies the engineering decisions and balances that must be weighed to provide the best solution within limiting parameters and the considerable effort this may take…

It is pleasantly surprising to find a revival in sandstone acidizing. For many years, sandstone acidizing was becoming almost a lost art, overshadowed by carbonate acidizing and hydraulic fracturing.
-
The authors describe a self-breaking, formation-damage-free, novel nanoparticle-based gelled-acid system to replace polymer-based gelled-acid systems.
-
This paper illustrates a novel methodology that enabled the safe application of coiled tubing abrasive perforation to increase production in a sour horizontal extended-reach oil producer.
